Definitions

  • ABSTRACT An umbrella having a tubular stem, a handle member housing a power source attached to one end of the tubular stem, and an electric lamp mounted on the other end of the tubular stem, at the top of the umbrella.
  • Water-proof seals are provided at each end of the hollow tubular stem by a solid terminal plug press-fitted into a synthetic resin sleeve which in turn is pressfitted into the tubular stem.
  • FIG. 1 A first figure.
  • This invention relates to an improved umbrella of the type having an electric lamp attached to its top to which electric power is supplied from dry cells housed in a cavity of the handle.
  • This invention is concerned with the problems of traffic safety and, in particular, the problem of pedestrian safety.
  • Rainy nights, often accompanied by fog, are occasions of extremely low visibility and, therefore, represent a high degree of danger to pedestrians.
  • Umbrellas equipped with electric lights have previously been proposed as a means of increasing pedestrian safety.
  • the prior art umbrellas of this type are generally of a structure having an electric wire running through a hollow tubular stem portion of the umbrella. These umbrellas generally have spring actuated latching means mounted through the tubular stem. The apertures provided for these latching means allow water to enter into the interior of the hollow stem, which ingress frequently causes corrosion and failure at the electrical contacts. Also, these prior art umbrellas are not designed in such a manner to facilitate repair or replacement of the electrical contacts.
  • the electric wire within the stem is slack.
  • the slack wire tends to bind or jam latching means located within the stem.
  • the electrical wiring also tends to bind on pins inserted through the tube for securing the latching means, handle and other attachments to the umbrella.
  • an umbrella carrying an electric light mounted at its upper extremity, on one end of a tubular stem, and having a power source housed within its handle, is provided with watertight seals at both ends of the tubular stem to protect the electrical contacts at the lamp and at the power source from any water which might enter into the interior of the stem member.
  • the structure of the umbrella of the present invention includes electrical wiring which connectsthe lamp with the power source and which is in tension so as to avoid binding with latching members and other attachmentsto the stem section.
  • the water-tight seals at each end of the hollow tubular stem section are in the form of a metal plug, which also serves as an electrical contact, press-fitted into a resilient bushing or sleeve member which in turn is pressfitted into the hollow of the tubular stem member.
  • the handle of the umbrella carries the power source and is provided with a switch for turning the electric light on and off.
  • Still another object of the present invention is to provide such an umbrella having easy access to the electrical contacts for purposes of repair.
  • FIG. 1 is a view, partially in longitudinal crosssection, of one embodiment of the present invention
  • FIG. 2 is a cross-sectional partial enlarged view of the umbrella shown in FIG. 1;
  • FIG. 3 is a view similar to the portion of FIG. 2 but showing another embodiment of the umbrella of the present invention.
  • FIG. 4 is a perspective view of the umbrella, partially in cross-section.
  • FIGS. 1 and 2 show one embodiment of the present invention.
  • FIG. 1 shows an umbrella having a tubular midsection or stem 10 and an upper ferrule or bushing 12 which is attached to the end of stem 10 by means of a pin 14.
  • Mounted in the upper ferrule 12 is an electric bulb 16 and a cap 18 which encases the electric bulb 16.
  • the lower end of the stem 10 is also provided with a bushing 20 which is secured to the stem 10 by means of a pin 22.
  • Removably attached to the bushing 20 is a cylindrical handle 24 which houses the power source 26, dry-cell batteries.
  • a resilient sleeve member or bushing 28 made from a synthetic resin and provided with an axial bore 30. Extending through the axial bore 30 is a bare end portion 34 of a synthetic resin covered wire 32 which connects the power source 26 to the bulb 16.
  • the bare end portion 34 is first pulled out of the sleeve 28 to a required length, and then the shank 38 of a metal terminal plug 36 is press-fitted into the bore 30.
  • the terminal plug 36 is designed to contact the bottom terminal of bulb 16.
  • the press-fit secures the bare end 34 of the wire 32 in the bore 30 between the sleeve member 28 and the shank 38 of the terminal plug 36.
  • the terminal plug 36 is constructed of a material that will provide a resilient contact with the bottom terminal of the bulb 16;
  • the bushing 28 serves as an insulator, isolating the'bottom terminal -17 of the bulb 16 from the metal tube 10.
  • a terminal plug 40 is likewise press-fitted into the axial 'bore 44 of an insulating bushing member 42 which, in turn, is press-fitted into the lower end of the stem 10 to provide a contact with the dry-cells housed in the handle 24.
  • the handle 24 and the stem 10 are also press-fitted together by means of a conductive bushing 20.
  • Protruding from the bottom of the handle 24 is a switch 46 by which the bulb 16 may be turned on and off.
  • One pole of the power source 26 communicates through wire 32 with the metal terminal plug 36, which, in turn, is in contact with the bottom terminal 17 of the bulb 16.
  • the other pole of the power source 26 communicates with the other terminal of the bulb 16 (the metal threaded portion) through the switch 46, the conductive cylindrical handle 24, the conductive bushing 20, the conductive stem 10, and through the conductive ferrule 12.
  • the assembly procedure previously described is repeated to affix the bare end 34 of covered wire 32 to the terminal plug 40.
  • the bare end 34 is first pulled out from the sleeve 42 to a required length and then the shank of the metal plug or terminal 40 is press-fitted into the axial bore 44 to rigidly mount the terminal therein and to secure the bare end 34 of the wire 32.
  • This provision permits the easy installation of an electric wire within the stem with the wire having a minimum length to bring the wire into tension when installed. Tension in the wire 32 precludes the possibility of incurring mechanical problems such as the binding of the latch means 48, etc.
  • the wire installation procedure described above may be used to seal only one end of the tubular stem, while the other end of the wire may be affixed to the terminal by any conventional means.
  • the combination of the resilient synthetic resin insulator bushings and the solid metal terminal plugs provides water-tight seals at both ends of the stem.
  • the bared ends of the wire are also isolated from the interior of the stem by these seals. Accordingly, even if rain water leaks into the stem through slits provided for latching mechanisms, or the like, the seals will prevent water from gaining access to either the electrical contacts for the bulb or the power source. This feature avoids potential electrical problems due to corrosion or short circuiting caused by water accumulated within the stem.
  • FIG. 3 shows another embodiment of the umbrella of the present invention.
  • the embodiment of FIG. 3 provides an improvement at the terminal connection for ease of repair when an electric failure occurs.
  • access to the terminal 36 is difficult because of the construction.
  • the embodiment of FIG. 3 solves this problem by providing the stem 52 with a second ferrule or bushing 54 in addition to bushing 58, which latter bushing is similar in design to bushing 12 of the embodiment of FIG. 1.
  • This second bushing 54 is rigidly affixed to the end of the tubular stem 52 and secured by means of pin 56.
  • Bushings 54 and 58 are threaded together to allow for access to the terminal plug 68.
  • a resilient insulating sleeve member 64 made from a synthetic resin.
  • the sleeve member 64 is provided with an axial bore 65 which receivesa'terminal plug 68 press-fitted therein.
  • the terminal plug 68 is provided with a shank portion 72 of hollow construction.
  • a bared end 67 of insulated wire 66 is inserted into the hollow shank 72 of the terminal plug 68.
  • the hollow shank 72 is then crimped to secure wire end 67 and to provide the shank wall 72 with a swaged configuration.
  • the head portion 70 of the terminal plug 68 is in contact with the bottom terminal of a bulb 60.
  • the bulb 60 is covered by a translucent cap member 62.
  • FIG. 4 shows the entire umbrella.
  • the cover or canopy 74 is supported by a plurality of main ribs 76 which are pivotally attached to an upper ferrule 78.
  • a number of auxilairy links 80 serve to support the main ribs 76 when the umbrella is open.
  • the auxiliary links 80 are pivotally attached to a lower ferrule 82 which is adfixed to a runner 84 that slides on the stem 52 and which is retained by latching means or detent 48 when the umbrella is open.
  • An umbrella comprising a hollow tubular member, a bushing member press-fitted into one end of said hollow tubular member, said bushing member being of a resilient, electrical insulating material and having an axial bore extending therethrough, and a metal terminal plug press-fitted into said axial bore of said bushing member, said bushing member and said terminal plug forming a water-tight seal at said one end of said hollow tubular member, means detachably connected to said tubular member for supporting an electric lamp in electrical connection with said terminal plug, means for supporting an electrical power source near the other end of said tubular member, and an electrical conductor wire disposed in said tubular member, one end portion of said wire being adapted for connection to said power source, and the other end portion of said wire being press-fitted between the inner surface of said axial bore of said bushing member and an outer surface portion of said'metal terminal plug.
